Flask Session Objects are special variables that persist for the duration of a browser session connected to a Flask app, allowing data to be accessible across different web pages without requiring repeated user input. These objects are similar to cookies but include a secret key for added security, although the data remains visible. They are particularly useful for applications requiring temporary data storage, such as a pay calculator app where a user’s hourly wage can be stored in a session and accessed by different web pages within the app. The implementation is straightforward, as session objects function like regular variables in code, following standard global and local variable rules. They offer versatile use cases, including personalizing user experiences, maintaining to-do lists, or managing online orders, by retaining data only for the session's duration. While the concept is simple, implementing session objects may require some experimentation to ensure code functionality.
